This is an instance where I’m “Liking” in recognition of your enthusiasm for the piece, and not my own appreciation. I have to admit having an unfair bias against the Grateful Dead, more based on some of their fans than anything else.

I do so very much regret, however, not going to a Dead show when I had the chance. I had several. Foolish, foolish me.

That’s fair.
I love the Dead – Garcia’s guitar does wonders for me, and I love so many of their songs. The story behind this one is an interesting one: http://www.youtube.com/watch?v=Q_fEzl5S0hE
I only saw the Dead twice – once in 77 and another time in 83 – memorable occasions.
